Hello dissident, and welcome to the Monastery!

The following line caught my eye:

filename => '@',            # @ = array (of char) = string

The comment suggests you may have a misunderstanding. In C, a string is indeed an array of char (i.e., characters). But in Perl, a string is a scalar, not an array. So if you want a single filename, you should say:

filename => '$',

By the way, you might also want to have a look at MooX::Struct by the Monastery’s own tobyink.

Update: For example:

use strict;
use warnings;
use MooX::Struct Document => [ qw($fileID $filename @tags) ];

my $doc = Document[ 123, 'SampleFileName', [ qw(tag1 tag2 tag3) ] ];

printf "File ID:  %s\n", $doc->fileID;
printf "Filename: %s\n", $doc->filename;
printf "Tags:     %s\n", join(', ', @{ $doc->tags });

[download]

Output:

22:52 >perl 1068_SoPW.pl
File ID:  123
Filename: SampleFileName
Tags:     tag1, tag2, tag3
